Most religions teach us about the existence of a sovereign God - the creator of everything. Some religions teach us the way of life and the practical ways to handle life and people alike. The culture of a certain place can also be based in the set of beliefs and practices set by its religion. The early civilisations show us that people wondered about creation so they created images and worship them. Religion is placed in the hearts of men but the paradigm shift in culture has melted the faith in human's heart. You can name all religions you know while not being a follower of any devotion and it is still culturally acceptable.
